Answer: The pressure in the can is 4.0 atm
Explanation:
According to ideal gas equation:
P = pressure of gas = ?
V = Volume of gas = 0.410 L
n = number of moles =
R = gas constant =
T =temperature =
Thus the pressure in the can is 4.0 atm
Answer:
A) 0.065 M is its molarity after a reaction time of 19.0 hour.
B) In 52 hours will react 69% of its initial concentration.
Explanation:
The reaction is first order in :
Initial concentration of =
a) Final concentration of after 19.0 hours=
t = 19.0 hour = 19.0 × 3600 seconds ( 1 hour = 3600 seconds)
Rate constant of the reaction = k =
The integrated law of first order kinetic is given as:
0.065 M is its molarity after a reaction time of 19.0 h.
b)
Initial concentration of =
Final concentration of after t =
Rate constant of the reaction = k =
The integrated law of first order kinetic is given as:
t = 185,902.06 s = ≈ 52 hours
In 52 hours will react 69% of its initial concentration.
